Hi
I pushed the commit 26eeb4e to [1]. The square peg now fits the round hole nicely, nothing else broke (we actually use it since a few weeks now). Thanks for your support Christian and Pirmin!

Hi Roman,
great to hear you managed to fit this square peg into a round hole (and broke all other platforms ;-).

The problem I care about is that scenarios using hybrid components don't work at runtime. For example run/lx_fs or run/netperf_lwip (uses linux_nic_drv):
[10:49:20.418] Warning: blocking canceled in entrypoint constructorAny idea whats wrong?
Actually, no. The information you provided about what happens could be called scarce at best. The core output about "blocking canceled" you cite happens if the core Linux process happens to receive a POSIX signal, which is in many cases SIGCHLD because any child exited.
I suggest you try to investigate this suspicion using the following hints.
- Analyze the syslog looking for messages about segmentation or protection faults.
- Pause execution of linux_nic_drv early on startup by calling magic extern "C" void wait_for_continue(); which waits for input on stdin.
- Try to attach a debugger to linux_nic_drv on the target.
- Maybe replace linux_nic_drv with a very simple hybrid Hello-World program.
Good luck
